    And you’ll only need about 320 million GWh per ~80kg person… plus 4 million GWh per kg of supplies, equipment and ship weight…

      Oh and also thats just the pure energy for acceleration/deceleration, not life support, steering, thrust ineffeciencies, take off, landing etc… 😅

      So 340 PWh per person. A couple of guys with a static bike and a dynamo and that’s it😜

      Note: the Earth receives 170 PWh of energy from the Sun in a year.

        Sounds feasible for a fusion reactor to provide at some point in the very distant future.

          Twice the full energy the Sun gives the Earth in a year for each person is not a future fusion reactor level. 😀
